Gap take pictures, according to photographed data, battery strings are adjusted to normal place by other mechanisms, then busbar is put electricity
The designated position of pond string end, makes busbar be superimposed with battery strings welding；
2) warm-up phase: circulation has the hot wind of small flow in the hot-air channel of welding unit, keeps the pressing in welding unit
Certain standby temperature；
3) heating period: the pressing in welding unit compresses the position that busbar is superimposed with welding, and hot wind block exports big flow heat
Pressing is heated to welding temperature by wind；
4) weld the stage: pressing persistently compresses busbar and welding, is kept for a period of time, by the tin layers of busbar and welding surface
Melt；
5) solidification stages: hot wind stops output, and the quick solidification under the cold wind effect that cold wind block exports of the tin after thawing will converge
Item and welding are combined together.
